2op Rn\ Mr, Kirby'j Account of the Ammophita, 



Collum infundibuliforme (w). 



Thorax fubcomprefTus pone alarum infertionem elongatus (.v). 

 Scutellum obfoletum. 



Ala plana?, venofae, anaftomofi obfoleta. 



Abdomen petioktum glabmm, acideo in foeminis recondito. 



Pedes longi, graciles, fetofi (y). Femora apophyfibus biarticulatis 

 infidentia (%). Tibiarum pcilicarum fpinulae interiores uno 

 latere pectinate {a). Tarji jquinque-articulati. 



Color niger, abdominis cingulo fermgineo. 



Many of thefe characters are peculiar to this genus, particularly 

 the form of the rofirum, maxilla, collum, and the pectinated 

 Jplnula of the pofterior tibia. Even colour, fo various in other 

 genera, in this feems characterise. To the above marks it might 

 be added, that, in all the fpecies I am going to defcribe, the under 

 fides of the pofterior tibia are covered with a fhort pale down. 



Character Essentialis. 



Rojlrum conicum inflexum, linguam bifidam exerens. 

 Antenna flliformes In omnifexu, articulis fubquatuordecim.

(.r) That part of the thorax which is behind the wings, I believe. I fball name upon a 

 future occafion the Metathsrax, as it is feparated in hymenopterous infecls both from the 

 thorax and fcutellum by a future, and in defcriptions often requires diftinft notice.

(a) Fig. io. I conjedure that this peden is ferviceable to the infecls of this genus in 

 the excavation of the little burrows, where they depofit the animal to which they have 

 committed an egg. When with their hind legs they diffipate (rufpando) the little heap 

 of fand from the, mouth of the burrow, which they had fcratched with their fore ones 

 from ks bottom, this peftcn will prevent the grains from pafflng between this fpine and 

 the bafe of the tarfus, which is alfo pectinated, although lefs vifibly. Fig. 9. a. !
